We planted and transplanted these seeds according to directions, but it seems like the stems are not growing correctly. Our fennel radish turnip iceberg lettuce and broccoli all look like this. Can you tell us what we should do?
It appears that they may have been lacking just a little in light as a seedling. This can cause spindly stems. Another cause can be lack of silica in soil, but this will be extraordinarily rare.
I think that leaving them to continue on will be best, as long as a soil test confirms that there are no deficiencies. Here are some articles that will help you to test your soil:

I grew fennel from seed but only had large stalks with approx 12" roots. No bulbs. Did I need more of a growing season?

Fennel does get tall so make sure the pot is large enough to handle its long taproot. Plus, it may not be getting enough light. You may need to add a grow light. Here is care info that may help:
